Recording device



Aug. 27, 1935. R. H. SEGAL RECORDING DEVICE Filed Sept. 15, 1933 TTORNEYPatented Aug. 27, 1935 UNITED STATES PATENT OFFICE 30mins.

This invention relates generally to recording devices, and particularlyto that class wherein the pliable element upon which the record isnoted, for instance paper, is wound upon one roller while simultaneouslybeing unwound from another.

An object of this invention is to provide a simple, efiicient andpractical recording device adapted for a multiplicity of uses.

A further object of the invention resides in the provision of arecording device wherein two rollers having wound thereupon a strip ofpaper are mounted and operated selectively in such a manner that thesaid paper will constantly remain taut, whereby the paper may be rolledand unrolled as desired without producing any slack.

A further object of the invention resides in housing in a recordingdevice a pair of spaced rollers having gears, and a rotatable operatingshaft intermediate the said rollers said shaft being provided with agear or gears, means being provided for operating the gears on therollers, selectively, by the gear or gears on the shaft.

A further object of the invention resides in providing in a recordingdevice a pair of spaced rollers and a rotatable operating shafttherebetween and pivoted to be swung towards the rollers, respectively,for engagement therewith. selectively, mechanism being provided tofacilitate said accomplishment.

This invention accordingly consists in the features of construction,combination of parts and in the unique relations of the members and inthe relative proportioning and disposition thereof; all as morecompletely outlined herein.

To enable others skilled in the art so fully to comprehend theunderlying features thereof that they may embody the same by thenumerous modifications in structure and relation contemplated by thisinvention, a drawing depicting preferred and modified forms has beenannexed as a part of this disclosure, and in such drawing, likecharacters of reference denote corresponding parts throughout all theviews, of which:-

Fig. l is a. top sectional view of a recording device according to theinvention and Fig. 2 is a sectional view along the line 2-2 ofFistl.

I and H2 carrying respectively Referring to the drawing, the housing Iis provided with a transversely disposed bracket ll. Rotatably mountedin bracket I3 and end 23 of housing I0 is a shaft I09 having fixedthereto the manipulatable knob H0. Loosely mounted for rotation on shaftIII! are the spaced gears III ratchet teeth II;

and Ill adapted for selective engagement with complementary teeth H andIII; respectively of a sleeve or clutch I I1 mounted for slidablemovement upon shaft I09, that is, clutch III may be slidably shiftedlongitudinally of shaft I09, by reason of a driving pin H8 fixed onshaft I09 cooperating with cam slot I I9 in the clutch.

The ratchet teeth H3, H5 and H4, H6 are such that rotation of knob IIIIin one direction will force teeth II6 to disengage from teeth Ill andcausing engagement of teeth H5 with teeth H3 and further rotation of theknob in the same direction will cause rotation of gear III, and sincepinion I4 is in mesh with gear III, roller R will rotate; while rotationof knob H0 in a counterdirection will force teeth II5 to disengage teethII3 and cause teeth H6 to engage teeth Ill. Consequently upon furtherrotation of knob H0 in the same direction, rotation of gear III iseffected and since the latter is in mesh with pinion 14', roller R willrotate.

A flexible sheet of record paper 39 is appropriately coiled about rollerR and passed over guide support 40 after it is suitably secured toroller B. When knob H0 is actuated a portion of the paper 30 registersbefore a suitable window ii at the upper part of the housing.

During rotation of one of the rollers by knob IIO, the other rollerserves as an idler and accordingly both rollers travel at equal orvarying rates of speed.

By the present arrangement, it will be observed that knob H0 is movableabout a. central axis only and hence in order to operate either roller,that is, the rollers selectively all that is required is the mereturning of the knob in one direction or the other.

Without further analysis, the foregoing will so fully reveal the gist ofthe present invention that others can by applying current knowledgereadily adapt it for various applications without omitting certainfeatures, that, from the standpoint of the prior art, fairly constituteessential characteristics of the generic or specific aspect of thisinvention, and therefore, such adaptations should and are intended to becomprehended within the meaning and range of equivalency of thefollowing claims:-

I claim:-

1. In a recording device for adjustably sustaining a flexible sheet, thecombination of, a housing, a pair of spaced and rotatable rollersadapted to move said sheet, means for selectively driving said rollerscomprising a rotatable shaft, a pair of spaced gears loosely mounted onsaid shaft and each having ratchet means, a clutch member common to saidratchet means and slidable longitudinally of said shaft, and meanscarried by said shaft for displacing said clutch memher to disengagefrom one of said ratchet means and engage the other of said ratchetmeans for driving one of said rollers to permit the remaining roller ofsaid pair of rollers to operate as an idler upon rotation of said shaftin one direction.

2. In a recording device for adiustably sustaining a flexible sheet, thecombination of, a

housing, a pair of spaced and rotatable rollers.

operatively moving said sheet, means for selectively driving saidrollers comprising a rotatable pair of rollers to operate as an idlerupon rotation of said shaft in one direction.

3. In a recording device for adjustably sustaining a flexible sheet, thecombination of, a housing, a pair of spaced rotatable rollers fordisplacing said sheet, a pinion associated with each roller, means forselectively driving said rollers comprising a rotatable shaft, amanipulator overhanging said housing and concentrically mounted on saidshaft, a pair of spaced gears loosely mounted on said shaft and eachcarrying ratchet means, a clutch member concentrically disposed andslidably mounted on said shaft and means carried by said shaft fordisplacing said clutch member to disengage from one of said ratchetmeans and engage the other of said ratchet means to actuate one of saidpinions and rotate an associated roller and permit the remaining rollerof said pair of rollers to operate as an idler upon rotation of saidshaft in one direction.
